This issue has been resolved in NSX-T Data Center 2.4.0 and cannot occur in future upgrades from that release.
Workaround:
To workaround the issue perform a manual repo sync using the API
POST https://NSX_Manager/api/v1/cluster/node?action=repo_sync
Example: curl -v -k -H "Content-Type:application/json" -u admin -X POST 'https://<NSX-Manager-IP>/api/v1/cluster/node?action=repo_sync'
